Thank you very much! I am (well, was) actually in need of a SERIOUS hair dye job in that photo... actually currently typing this with dye in my hair hahaha, i sometimes do it myself, or have my best friend who is a cosmetologist dye it for me. Always the same brand. Vegetable based hair dyes!
I have a post on my blog for more info on dying my hair
